Nasal Polyps

Nasal Polyps

definition:
Polyps formed by nasal mucosa.

etiology:
Polyp formation usually follows the edema and inflammation of a chronic allergic rhinitis, or comes from an acute or chronic sinusitis. If from an acute infection, they may regress once the infection has cleared. They are mostly found around the ostia of the maxillary sinuses, and when mature, resemble a peeled seedless grape.
